i have tried using ubuntu 10.04 and ubuntu 11.10 and both have the same problem the driver is detected by the additional propriety drivers wizard and after installation, ubuntu can't see except on wireless network which is not mine (and i can't connect to it as it is secured)
There are plenty of wireless networks around me but ubuntu can't detect them and if i tried to connect to one of them as if it was hidden connection time out.
lspci -nvn | grep -i net
04:00.0 Network controller : Broadcom Corporation BCM4313 802.11b/g/n Wireless LAN Controller [14e4:4727] (rev 01) 05:00.0 Ethernet controller : Realtek Semiconductor Co., Ltd. RTL8101E/RTL8102E PCI Express Fast Ethernet controller [10ec:8136] (rev 05)
lo no wireless extensions. eth0 no wireless extensions. wlan0 IEEE 802.11bgn ESSID:off/any Mode:Managed Access Point: Not-Associated Tx-Power=19 dBm Retry long limit:7 RTS thr:off Fragment thr:off Power Management:off
i guess it is something related to Broadcom driver .. but i don't know , any help will be appreciated
UPDATE: ok i installed a new copy of 11.10 to remove the effect of any trials i have made i followed the link (http://askubuntu.com/q/67806) as suggested
all what i have done now is trying the command
lsmod | grep brc and it gave me the following
brcmsmac 631693 0 brcmutil 17837 1 brcmsmac mac80211 310872 1 brcmsmac cfg80211 199587 2 brcmsmac,mac80211 crc_ccitt 12667 1 brcmsmac
then i blacklisted all the other drivers as mentioned in the link
the wireless is still disabled..
in the last installation installing the Brodcom STA driver form the additional drivers enabled the menu but as i have said before it wasn't able to connect or even get a list of available networks
so what should i do now ?
the output of command
rfkill list all rfkill list all
